Air Tightness Testing, building sound test and air permeability test

We are accrediited air tightness testers so you can have confidence in knowing that the certificates we issue will be accepted by building control, private inspectors and architects.

Air leakage test is another name for air permeability test or air tightness testing. We air test buildings across the country.

Being a registered air tightness tester means we can perform air pressure tests on new build houses and commercial buildings including;

Residential houses

Flats and Offices

Care homes

Warehouses, Shops and Club Houses

Shops, Leisure Centers and other commercial buildings.

We tell you the air tightness test cost up front. We keep the cost of the air permeability test low and retest on the same visit for free. We have tested hundreds properties providing free advice to help you get the best result first time. We provide a quick response when time is important.

We do new build air test all over England and Wales. We have tested properties for private developers who have built a single houses to builders and companies who have developed commercial buildings. Call now to book your air tightness test.

This will be to satisfy the requirements of Part L of the approved building regulations. House air tightness testing is what we do. We are registered which means we are authorised to test buildings and issue certificates for air leakage measurements.

Free initial visual site inspection upon arrival, we will let you know of any holes or areas of air leakage that we observe. This will allow you to make improvements to help you pass first time.

If the property doesnt pass first time, we will power the fan up and identify where the holes in the building are. We will give you time to fill the holes. As long as you fill the holes as part of the same site visit, we will retest the new build for no additional charge.

All our costs include all fees and certification, there are no hidden extras and best yet NO VAT.

You can fill holes with expanding foam, silicon or decorators calk. Sometimes its small things like calking the top of the skirting boards that makes the difference between a pass and a fail. if you have any questions, just call and ask.

You may need a building sound test inorder to satisfty part E of the approved building documents. This is normally for semi-detached dwellings and flats. In addition, depending on whether there are dwellings underneath or above the property, you may need impact as well as air bourne sound tests. We provided both building sound tests and certification.

You will need SAP calculations to satisfy building control and private inspection bodies. The SAP provides an energy performance certificate and demonstrates that thebuilding meets energy efficiency criteria set by the government.

During this weeks air tightness testing we noticed the following common areas where air is likely to leak into the property resulting in a lower rating.

seal holes under baths

One place to look is under the bath because often people think it doesnt matter because no one will see it. But the truth is the air tightness test cannot distinguish between between hidden or un hidden holes. You can see from the picture on the right that in this house there is a massive hole where the air is being drawn out off. Seal every where!
